fix: rank a console first for its own name

The PlayStation 2 page holds every word of "playstation bios" and pagefind ignores the words a page has that the query lacks, so its own body matches put it first. A console whose every word another system page's consoles also hold is now written again in an `exact` field (weight 20). File names reach the `files` field as their parts: whole names let "ds" reach twelve dsi_* names on the DSi page. `consoles` weighs 100 so an emulator named after its console (Saturn.emu) comes second, and `aliases` 10 so the Nintendo page keeps "gba bios". The gate runs both directions of the PlayStation, Game Boy, DS and Wii pairs and Saturn.
